Introducing scdoc, a man page generator May 13, 2018 on Drew DeVault's blog

A man page generator is one of those tools that I’ve said I would write for a long time, being displeased with most of the other options. For a while I used asciidoc, but was never fond of it. There are a few things I want to see in a man page generator:

  1. A syntax which is easy to read and write
  2. Small and with minimal dependencies
  3. Designed with man pages as a first-class target

All of the existing tools failed some of these criteria. asciidoc hits #1, but fails #2 and #3 by being written in XSLT+Python and targetting man pages as a second-class citizen. mdocml fails #1 (it’s not much better than writing raw roff), and to a lesser extent also fails criteria #21. Another option, ronn meets criteria #1 and #3, but it’s written in Ruby and fails #2. All of these are fine for the niches they fill, but not what I’m looking for. And as for GNU info… ugh.

So, after tolerating less-than-optimal tools for too long, I eventually wrote the man page generator I’d been promising for years: scdoc. In a nutshell, scdoc is a man page generator that:

I recently migrated sway’s manual to scdoc after adding support for generating tables to it (a feature from asciidoc that the sway manual took advantage of). This change also removes a blocker to localizing man pages - something that would have been needlessly difficult to do with asciidoc. Of course, scdoc has full support for UTF-8.

My goal was to make a man page generator that had no more dependencies than man itself and would be a no-brainer for projects to use to make their manual more maintainable. Please give it a try!


  1. mdocml is small and has minimal dependencies, but it has runtime dependencies - you need it installed to read the man pages it generates. This is Bad. ↩︎

Status update, May 2024

Hi! Sadly, I need to start this status update with bad news: SourceHut has decided to terminate my contract. At this time, I’m still in the process of figuring out what I’ll do next. I’ve marked some SourceHut-specific projects as unmaintained, such as sr.ht-…

Automatic case design for KiCad

I don't generally get along great with CAD software with the exception of KiCad. I guess the UX for designing things is just a lot simpler when you only have 2 dimensions to worry about. After enjoying making a PCB in KiCad the annoying for me is alwa…

The floor is lawa!

And now for something completely different… When was the last time you were excited about a simple window with nothing but a single background color? Well, I currently am. Let me tell you about it… This window is notable, because it was created using the ”pu…
